I think I've mentioned this before, but after a bunch of replaying, I say it bears rementioning. Go and install Truck Dismount, from this address. It's just horrible, yet irresistible, at the same time. For fun, don't go for high scores, because it just seems to be a contest, then, at who can keep the guy's head stuck in the grill of the truck for the longest. I say try the most painful looking stunts possible, and watch them over and over again.
